IMPROVEMENT IN GHURNS.

TO lALL WHOM IT MAY GONQERN: v

i Be it known that we, DANIEL H. CARPENTER, of H'ector, in the county of Schuyler, and State of New York, and HIRAM L. SLnGHT, of Lodi, in the county of-Seneca,land State of New York, have invented anew and useful Improvement in Churns; and we do hereby declarethat the following is a full, clear, and exact descrip- 'tion thereof, which will enable those skilled in the art to make and use thel same, reference being had to the accompanying drawings, forming part of this speciiicatiolri.` v

. This invention relates Atoa new and useful improvement inthe methodof constructing churns forgdairy purposes, whereby the ordinary single or double-dasher barrel-churn is operated with much less labor or exertion of strength than when operated in the ordinary manner; and the invention consists in attaching the churn to u, swinging frame, ,and in oscillating a crank-shaft" by the swinging motion'of the frame, and operating the churndasher thereby, as will be hereinafter more fully described. p

The drawing represents 'a vertical sectional elevation of the arrangement, showing portions of the stationary and. swinging frames with the churn attached thereto. i

A represents a stationary frame, upon whichthe churn and swinging frame are supported. is the churn, which stands upon a. platform, C, of the swingingframe. D represents the upper portion of the swinging'frame, which portion is composedvof two side pieces, (only one of which is seen in`the drawing,) marked E. I These side pieces Eare` connected together by a transverse ,bar, F, through which the flasher-rod Gr of the churn passes. H represents a crank-shaft, which is connected'jwith the end of the dasher-rod` by the connecting-rod I. This crank-shaft Hhas its' bearings in the stationary frame A, at its ends,.an`djust inside of eaelibearing there is rigidly attached to the cranklshaft a friction-roll,.f, through which the crank receives its oscillating motion. J represents arms, which branch from th side' pieces E of the swinging frame, the upper ends of whiohare connected `togetherloy segments forming the upper end of the frame, as seen at D. Theside pieces E actas levers in this connection, the fulcrum ofv which is at the pin z', which is attached to the frame A. The upper ends of these pieces are slotted,A las seen at k, which allows them a longitudinal motion. -The weight of the churn and swinging frame rests upon the rollsf onth'e shaft H. The churn is put in motion by working the rodIi back and forth. The whole weight vbeing suspended on the shaft H through the rollsf, the motion is vgoverned by the pin oneach side, so the 'segment D traverses the rollersf, and the weight on these rollers is sucient to`partially rotate the crank-shaft H. This'partiai rotation gives motion tothe dasher-rod G through the connecting-rod I'andcrank-shaft H. Y

It will be seen that the reciprocating horizontal motion imparted tothe swing frame by.the rod L, imparts the required and usual reciprocating motion tothe dashes-rod of the churnand that when in operation the gravity andmomentum of lthe frame and the loaded churn combine to aid in the operation, thus rendering the tedious and laborious process of churning butter comparatively easy'.

Having thus described our invention, we claim as new, and desire to secure by Letters Patcnt- 1. The stationary frame A, the swinging frame composed of the partsC, E, J", and D," arranged substantially as described for the purpose set forth. l

2. The fulcrum-pin i, slot c, connectiug-rod I, shaft H, witlrthe friction-rollsf, in combination with the swinging frame, the whole arranged and operating substantially-as and foi-'the purposes described.
